The utility model provides a concrete bridge subsides detection device, including annular base 100 and adjustment mechanism, annular base 100 cover is established on support column 300, be provided with annular slide rail 120 on the annular base 100, set up an instruction ball 170 and two first pellets 160 in the annular slide rail 120, the quality of two first pellets 160 is the same, the quality of instruction ball 170 is greater than the quality of first pellets 160, be provided with first elastic component 150 between two first pellets 160 and the instruction ball 170, the both ends of first elastic component 150 all are provided with first sliding plate 140, during initial state, three first elastic component 150 all are in compression state so that the first sliding plate 140 at first elastic component 150 both ends and two first pellets 160 and the butt of instruction ball 170, two first pellets 160 and the even interval distribution of instruction ball 170 are in annular slide rail 120, adjustment mechanism is used for adjusting the position of instruction ball 170. When the support column 300 is not tilted, i.e., the support column 300 is in a normal state, the indication ball 170 and the two first beads 160 are uniformly spaced and relatively stationary distributed in the annular slide rail 120, and when the support column 300 is tilted, there are two cases in which the position of the indication ball 170 is not adjusted if there is no adjustment mechanism.
First case: when the direction of inclination of the support column 300 is not on the perpendicular bisector of the connecting line of the two first pellets, the indication ball 170 and the two first pellets 160 slide in the annular slide rail 120 under the action of gravity, because the mass of the indication ball 170 is greater than that of the first pellets 160, when the indication ball 170 slides in the annular slide rail 120, the indication ball 170 slides to the lowest position in the annular slide rail 120, namely, the inclined position of the support column 300, and when the two first pellets 160 and the indication ball 170 are stationary, as shown in fig. 9, the arrow indication direction is the inclined direction of the support column 300, the two first elastic members 150 are shortened, one first elastic member 150 is extended, the connecting line of the two first pellets 160 and the position of the indication ball 170 forms an isosceles triangle, the position of the indication ball 170 is the inclined position of the bridge, the inclined direction is the center of the support column 300 points to the direction of the indication ball 170, and the sensor (not shown in the figure) is arranged on the annular base 100, and the inclined direction of the bridge 170 is further sensed by the position of the indication ball 170.
Second case: when the direction of the bridge inclination is on the perpendicular bisector of the connection line of the two first pellets 160, under the action of gravity, the two first pellets 160 move in the annular slide rail 120, as shown in fig. 11, the arrow indicates that the direction of inclination of the support column 300 is the direction of the arrow, the two first pellets 160 move synchronously and the distance of movement is the same, the indicator 170 is stressed and balanced but does not move in the annular slide rail 120, at this time, the indicator 170 is in the second position, that is, the position of the indicator 170 is opposite to the position of the support column 300 where the inclination occurs, so that an adjusting mechanism is introduced to adjust the position of the indicator 170, so that the position of the indicator 170 is the position of the support column 300 where the inclination occurs, the adjusting mechanism can make the distance of the movement of the two first pellets 160 in the annular slide rail 120 different, and under the action of the first elastic member 150, the indicator 170 is stressed and then makes the indicator 170 slide in the annular slide rail 120, and the position of the indicator 170 returns to the first condition, that is the position of the support column 300 where the inclination occurs. The inclination direction of the bridge can be determined by sensing the position of the indicating ball 170 through the sensor, the inclination degree of the bridge can be judged by sensing the compression degree of the first elastic piece 150 through the sensor, the inclination direction and the inclination degree of the bridge can be accurately monitored, and the bridge inclination early warning can be sent out at the first time.
Specifically, as shown in fig. 3 and fig. 4, the two side walls of the annular slide rail 120 are provided with the first annular slide groove 121, the two sides of the first slide plate 140 are provided with the first slide protrusions 141, the first slide protrusions 141 are located in the first annular slide groove 121, so that the first slide plate 140 can move along the first annular slide groove 121, and the three first elastic members 150 are in a compressed state, so that the first slide plate 140 is abutted against the two first pellets 160 and the indicating balls 170, and when the support column 300 is inclined, the two first pellets 160 and the indicating balls 170 move in the annular slide rail 120, and the first slide plate 140 can also be abutted against the indicating balls 170 and the two first pellets 160 under the action of the first elastic members 150, so that interaction between the three is ensured.
In a further embodiment, as shown in fig. 3 and 6, the adjusting mechanism includes a second small ball 230, two connecting plates 240 are fixedly disposed on two sides of the second small ball 230, two second elastic members 260 are connected to two sides of the two connecting plates 240, one ends of the two second elastic members 260, which are far away from the connecting plates 240, are connected to a second sliding plate 250, two side walls of the annular sliding rail 120 are further provided with a second annular sliding groove 122, the second annular sliding groove 122 is parallel to the first annular sliding groove 121, the second annular sliding groove 122 is located above the first annular sliding groove 121, second sliding protrusions 241 are disposed on two sides of the two second sliding plates 250, the second sliding protrusions 241 are located in the second annular sliding groove 122, third sliding protrusions 270 are disposed on two sides of the two connecting plates 240, and the two second sliding plates 250 and the two connecting plates 240 can slide along the second annular sliding groove 122, so that the second small ball 230 can slide along the second annular sliding groove 122. As shown in fig. 3 and 8, the two second sliding plates 250 and the second elastic members 260 are connected at the same side and abut against the two first sliding plates 140 between the two first beads 160, and initially, the two second elastic members 260 are in an original long state, and the elastic coefficients of the two second elastic members 260 are different. When the direction of inclination of the support column 300 is on the perpendicular bisector of the line connecting the two first pellets 160, the situation that the position indicated by the indication ball 170 is opposite to the inclined position of the support column 300 is caused, and the two first pellets 160 move in the first annular slide rail 120 under the action of gravity, but because the first sliding plate 140 of the first pellets 160 abuts against one side of the second sliding plate 250 and the elastic coefficients of the two second elastic members 260 are different, the stress of the two first pellets 160 in the annular slide rail 120 is different, and the indication ball 170 is unbalanced, so as to slide in the annular slide rail 120.
For example, assuming that there is no adjustment mechanism, when two first balls 160 move, the first elastic member 150 between the two first balls 160 shortens, and the first elastic member 150 between the indicator ball 170 and the first balls 160 stretches, so that the state shown in fig. 11 is formed, when the elastic coefficient of the second elastic member 260 on the left side of the second ball 230 is greater than the second elastic coefficient on the right side of the second ball 230, as shown in fig. 8, when the two first balls 160 move, the first ball 160 on the left side is pulled by the second elastic member 260 on the left side more than the first ball 160 on the right side is pulled by the second elastic member 260 on the right side, and the two first balls 160 are stressed differently, so that the distance that the first ball 160 on the left side moves is smaller than the distance that the first ball 160 on the right side moves, so that the indicator ball 170 is pulled by the first elastic member 150 on the left side to the right side, and the state changes, as shown in fig. 12 and fig. 13, when the arrow indicates the direction of inclination of the support column 300, and when the second ball 170 is not slid by the second ball 170, i.e. when the second ball 170 is not slid at the right side of the second ball 170, the second ball 170 is at the right side, and the rest, the second ball 170 is not slid, and the second ball 170 is at the position of the ball 170; when the elastic coefficient of the second elastic member 260 at the left side of the second ball 230 is smaller than the second elastic coefficient at the right side of the second ball 230, the same is the same as the case where the elastic coefficient of the second elastic member 260 at the left side of the second ball 230 is larger than the second elastic coefficient at the right side of the second ball 230, but the directions are opposite, and the description thereof is omitted.
In another embodiment, instead of two first balls 160 and the indicator balls 170, three first sliding blocks may be disposed in the annular sliding rail 120, where the two first sliding blocks have the same mass, the other first sliding block has a mass greater than that of the two first sliding blocks, one of the first sliding blocks having a large mass is disposed as a sliding block indicating the inclined position of the support column 300, and an elastic member is connected between each two adjacent first sliding blocks, and the three elastic members are in an extended, compressed or original length state synchronously.

When the support column 300 is inclined, the inclined direction is not on the perpendicular bisector of the connecting line of the two first pellets 160, the two first pellets 160 and the indicator ball 170 move in the annular slide rail 120 under the action of gravity, at this time, the second pellets 230 also move under the action of gravity, but the movement of the second pellets 230 does not affect the movement of the two first pellets 160 and the indicator ball 170, and since the mass of the indicator ball 170 is greater than that of the first pellets 160, the indicator ball 170 slides to the lowest position on the annular slide rail 120, and when the two first pellets 160, the indicator ball 170 and the second pellets 230 are stationary, the position of the indicator ball 170 is the inclined direction of the support column 300, and the sensing device can sense the position of the indicator ball 170, so as to learn the inclined direction of the support column 300, and can primarily judge the inclined degree of the support column 300 according to the compression degree of the first elastic pieces 150 on both sides of the indicator ball 170.
When the support column 300 is inclined, the inclined direction is on the perpendicular bisector of the connecting line of the two first small balls 160, because the elastic coefficients of the second elastic members 260 at both sides of the second small ball 230 are different, when the two first small balls 160 slide in the sliding rail, the second sliding plates 250 of the two second elastic members 260 abut against the first sliding plates 140 of the two first small balls 160, so that under the action of the second elastic members 260 with different elastic coefficients, the moving distance of the two first small balls 160 in the annular rail 120 is different, so that the stress of the first elastic members 150 at both sides of the indication ball 170 is different, and the indication ball 170 slides in the annular rail 120, so that the position of the indication ball 170, which is caused by the fact that the indication ball 170 does not slide in the annular rail 120, is opposite to the inclined direction of the support column 300, is caused to slide in the annular rail 120 to the lowest position, that is, the position of the indication ball 170 is the inclined position of the support column 300, and the first elastic member 300 is sensed by the sensor, and the degree of the inclination of the support column 300 is sensed.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
